West and North Zone qualified for the semi-finals of the Duleep Trophy after taking a first-innings lead vs North East Zone and East Zone respectively.
While West obtained a massive 367-run lead over North East Zone at the M A Chidambaram Stadium and opted for batting practice on the fourth and final day on Sunday, North rode on a superb ton by debutant Yash Dhull (193) to overhaul East Zone's total.
The Ajinkya Rahane-led West Zone were 268 for five when the match ended. Aith Sheth remained not out on 102 (101 balls, 10 fours, 1 six), and Shams Mulani fell for 97 (115 balls, 12 fours), as the match meandered to a draw.
North East bowlers did a lot better in the second innings and had their opponent three down for 49 and 65 for 4 before Mulani and Sheth came together for a 179-run
partnership.
Medium-pacer Dippu Sangma (3 for 70) removed Het Patel (7), Rahul Tripathi (24) and Hardik Tamore (24) to keep the West batters in check.
In Puducherry, North, resuming on overnight 433 for three, added a further 112 runs before being dismissed for 545. Himanshu Rana made 81 and captain Mandeep Singh hit a patient 63.
North Zone looked set for a huge total but the hard-working left-arm spinner Shahbaz Ahmed came up with a five-wicket haul to restrict Mandeep Singh & Co.
Shahbaz Ahmed's scalps included Mandeep, Himanshu Rana, and Nishant Sindhu. He ended the 131-run stand between Mandeep and Himanshu Rana which went a long way in helping East stop North's charge.
Earlier, youngster Yash Dhull struck a magnificent 193 off 234 balls to help North Zone to a comfortable position.
